A Wonderleaf question
How do storms form?
a real page from the book
Storms form when warm, damp air rises and cooler air moves in underneath it. As the rising air cools, its water vapor turns into cloud droplets and rain. If the air keeps rising, the system can grow stronger, with wind and clouds feeding each other.
That is why many storms fade after sunset or over cooler ground: their supply of heat and moisture gets weaker. In a thunderstorm, the same cloud can be full of climbing air, falling rain, ice, and rumbling electric sparks.
